Additional information

A bacteria growth inhibition test was performed under GLP following the OECD 209 guideline (CG, 1990). In this study, activated sludge of a predominantly domestic sewage treatment plant was exposed to test substance concentrations of 0 (control), 1, 3.2, 10, 32 and 100 mg/L. No effects were noted up to the highest concentration tested. Based on these findings, the 3 -h IC50 was determined at >100 mg/L (nominal concentration).
